Challenges we ran into
⚠️ Challenges We Faced
Building PromptHub was a thrilling ride — but not without its share of speed bumps:
🔗 Frontend + Backend + Blockchain Integration
One of our biggest challenges was bringing together three powerful yet independently developed modules — the frontend (React + Vite), the backend (Node.js + MongoDB), and the PoB Token smart contract (Solidity on Ganache). Ensuring smooth interaction across different tech stacks and asynchronous environments required careful coordination and refactoring.
🧠 State Management Across Domains
Since different members worked on different layers, syncing the user session data (login, wallet addresses, votes) across frontend, smart contracts, and the database was extremely tricky. We had to write multiple bridge utilities and use consistent schemas to enable seamless data flow.
🚧 Local Blockchain Conflicts
While developing on Ganache, we faced version mismatches and syncing delays between deployed smart contracts and frontend instances. The MetaMask-Ganache connection often lost sync during state changes, causing unexpected UI behavior.
🚀 Unified Deployment
Merging everything into a single deployable build proved complex. Vite needed its own build logic, the smart contracts needed compiling and migration, and the backend had to stay accessible to both. Coordinating these processes in a production-ready manner was one of our steepest learning curves.
🧪 Preview Errors & CI/CD Hiccups
Vite's preview sometimes showed a blank screen due to animation/state load mismatches. We had to debug async React rendering issues and optimize Framer Motion transitions to ensure the app loaded cleanly.
👥 Team Merge and Git Conflicts
As our team members worked on parallel modules, we occasionally ran into merge conflicts and version inconsistencies — especially with shared configs like .env, contract ABIs, and proxy URLs
